Abstract
A partial converter system (2) includes a branch pair (3) comprising two series-connected driven power semiconductor switches with each having a diode reverse-connected in parallel. The branch pair is connected in parallel with branch pairs (13,14) connected to an electrical energy store (4). A junction point of the switches of branch pair (3), forms a terminal (18) of converter system. An Independent claim is also included for method of operating voltage maintenance device.
